The future of Wireless Sensor Network is bright because it consists group nodes or devices.Each device has ability to communicate with other devices and they convey their observations through other devices to a destination. Most importantly with developing technology, wireless sensor networks smaller and more cost effective because of miniaturization process.
By means of developments and miniaturization, wireless sensor network technology has grown rapidly in those 10 years. Sales numbers are proof of this development. In USA, between 5 and 7 billion dollar has been obtained from this sector. In the future, I believe that people will need ZigBee Health Care much more compare to today. In the meanwhile, my belief is supported by Forrester Research. According to their research, they expect US chronic disease device market will grow from 3.8 billion dollar to 26 billion dollar in 5 years.
Apart from USA, in European Union and Japan, market has been growing because of elderly population and it is expected that total potential market will be 87.8 million people.
It is good to take a look US based Chronic Disease Self-Management Program for understanding the importance of ZigBee Health Care. It is a program which uses for different chronic illnesses for example arthritis, diabetes, heart diseases etc. At the end of the program, there is an evaluation and this evaluations show that the patients who took part in this program, improved their health status and behaviours. Although it helps to people to recover, there is a debate about cost because it is around 200 dollar per patient which is quite high for many people. After this program is automated through wireless sensors, patients pay quite less comparatively which results in spread this program all over the world.
